Great info!!
I went out to the workshop to see if I could find an auxiliary input to try my iPhone and there was nothing on the front (except a headphone jack). It would require dismantling everything in the stereo cabinet to plug it in. But since the cassette player and dvd player are both hooked into the back of the receiver I should be able to do the same thing with the iPod?
Let's see, if I give him the iPod, the DVD player and all the DVDs can go...

He'll probably commute by bicycle tomorrow and I can check out the car.
My other question is, is the interface for the Nano the same as a full size iPod (in case he wants to upgrade at some point to something that you can plug the iPod into directly)?
